Preparation for work on translations
by Slávek Banko 01 Mar '19

01 Mar '19

Hi all, those of you who have been here for a long time might recall that when I joined the community I assumed that my tasks would be only two: backport patches to the stable TDE series and work on translation. Over time, it turned out that my tasks on the project would be bigger. However, work on translations is still a postponed task. Recently, I have devoted some time to the tasks that are essential to move us forward with the work on translations. Therefore, I would like to inform you about the results and related plans. I apologize for long email. 1. Unnecessary updates of POT files during package build I observed that during the DEB packages build, an attempt was made to update POT files. However, this step makes no sense. Bundling usually takes place in dedicated pure chroot. Therefore, the result of updating POT files would be discarded anyway. So this is unnecessary work. At the same time, the extractrc tool is used during the POT files update. But this tool is part of the tdesdk-scripts-trinity package. Therefore, when building other packages, it is usually not present. So updating POT files during building could not work well. That's why I already removed these unnecessary updates of POT files while building DEB packages. 2. Do we still need to use the old modified version of xgettext? I found out what the current status is and whether there are still reasons to use the old modified version of xgettext (kde-xgettext). Patches for the old version solve two things: a) adding a way to enter plural forms of strings b) adding a way to enter translation context The current versions of gexttext already have both of these options, but they seem to be implemented in a different way. Before we can start using standard xgettext in TDE, we will need to add support for a new way of plural forms of strings and translation contexts. So far, we need to continue using an old modified version of kde-xgettext. 3. Can modern gettext replace the extractrc tool? Modern versions of gettext can handle XML files. We use XML files for 'kcfg', 'rc' and 'ui'. Using ITS support in gettext, there is a way to define which texts are to be extracted for translations. I tested this option, but I encountered some problems: a) Tags are written in strings as html entities: < / > / &. After extraction using xgettext, are left in this form. But the extractrc tool convert them to the appropriate characters '<', '>', '&'. I did not find a way to do this with xgettext and ITS. b) XPath is used to determine which strings are to be extracted from XML files. Files 'kcfg' use their own XML namespace and I did not find a way how to enter XPath to work properly with ITS in xgettext. That's why I decided it was better to continue using the extractrc tool. 4. How do we create and update POT files? In order to provide strings for translation, we first need to create and update POT files. The best place for these files is right in the source code – in GIT. Therefore, these files need to be maintained independently of the building binaries. Therefore, it is obvious that for this task it is not a good time during the build binary packages, nor the usual use of Automake or CMake. Although the usual use of CMake with CMakeLists.txt for updating POT files is not a good choice, using CMake as such seems to be a good idea. CMake allows using the -P option to process a different file than the usual CMakeLists.txt. In this case, it does not create build folder, it does not create a cache - exactly as it suits us for our purpose. I decided to use the name CMakeL10n.txt. I have prepared the CMake module TDEL10n.cmake. This module provides functions for simplifing directories handling – function tde_add_l10n_subdirectory as the equivalent for add_subdirectory and function tde_auto_add_l10n_subdirectories as an equivalent for tde_auto_add_subdirectories. And above all, the tde_create_l10n_template macro that provides POT files generation. This macro provides some benefits that seemed useful: a) If resource files are processed – for example, *.ui, the work file "rc.cpp" is commonly used to save extracted strings for translation. This file is then processed by kde-xgettext. Links to the original location of strings in the resulting POT file then refer to this "rc.cpp", which is not very useful. The tde_create_l10n_template macro performs additional processing by replacing references to "rc.cpp" with references to the original resource files. Therefore, the POT file does not refer to a non-existent "rc.cpp" file, but to real locations in resource files. b) When a new POT file is generated, a comparison is made with the original POT file. If only the date of POT file generation is changed, the original POT file will be left unchanged. This prevents unnecessary POT file updates. This will allow to run a regular update of POT files without causing unnecessary commits. 5. What's next? For revisions and comments, I created a pull request containing a CMake module TDEL10n.cmake: https://mirror.git.trinitydesktop.org/gitea/TDE/tde-common-cmake/pulls/2 ...and pull requests with a demonstration of use CMakeL10n in two modules: https://mirror.git.trinitydesktop.org/gitea/TDE/abakus/pulls/1 https://mirror.git.trinitydesktop.org/gitea/TDE/tdebase/pulls/19 After testing, we will need to add CMakeL10n.txt to generate POT files in all other modules. Once we have automated updating of POT files, translation work can begin! 6. How can users work on translations? I will leave the answer to this question for later. Whoever was more attentive could have noticed in several earlier commits that "something is being prepared" :) Cheers -- Slávek

Fwd: [britney]: Do you use --control-files or the "legacy package layout" in your derivative?
by Mike Bird 30 Dec '18

30 Dec '18

FWIW I don't know if this impacts the way that debs are built for TDE. --Mike ---------- Forwarded Message ---------- Subject: [britney]: Do you use --control-files or the "legacy package layout" in your derivative? Date: Sun December 30 2018, 11:13:00 From: Niels Thykier <niels(a)thykier.net> To: Raphaël Hertzog <hertzog(a)debian.org>, Matthias Klumpp <mak(a)debian.org>, Iain Lane <laney(a)debian.org> CC: "debian-release" <debian-release(a)lists.debian.org>, "debian-derivatives" <debian-derivatives(a)lists.debian.org> Hi, I am writing to you, because I know that you are (or have been) involved in setting up or maintaining a britney instance for a Debian derivative. If you are no longer involving please let me know who to contact instead (where applicable). We are considering to deprecate the "legacy package layout" and remove the "--control-files" option. 1) Debian no longer uses these two features in our production runs at all and now instead simply point britney at the metadata of a standard mirror. 2) The "--control-files" option has not being updated and currently generates incomplete Sources files for the target suite. We have no test cases to safe guard against that. As it is not a feature we use, it is unlikely to appear there. 3) The "legacy package layout" is currently used for tests and is unlikely to disappear immediately. However, if a better layout for test cases appear, we may migrate to it and remove the old code. How can I tell if I use these features? ======================================= Check your britney command line. If it includes "--control-files" then you are using both features (as "--control-files" only works with the "legacy package layout". Otherwise, check your britney configuration. If the path set for the "TESTING" configuration points to a standard APT mirror (with a Release file) you are unaffected by this mail. If it instead points to a file directory with some "Packages_X" files and a "Sources" file, you are using what I refer to as the "legacy package layout". You can also check the output with -v for a line like [1]. This determine if britney actually believes it is working with a standard mirror layout. If you use "--control-files": ============================= If you use "--control-files", then you can probably discard it. If you rely on the updated target suite, please consider reusing whatever tooling you use to generate your source suite data to also generate the target suite. This ensures you have a sane full data set for both source suite(s) and target suites. If you use the legacy package layout: ===================================== If feasible, consider migrating to using a standard mirror layout (e.g. if you have a local mirror on the machine running britney). This also enables you to remove the "ARCHITECTURES" and "COMPONENTS" fields from your configuration file as britney simply reads those from the Release file of the target suite. If the mirror format it not an option, please let me know about your use case to see if there is a better alternative. Other bits while we are in contact. :) ====================================== Improving britney: ------------------ We are accepting contributions to britney via salsa.debian.org[2] in form of Merge Requests and bug reports via the BTS as usual (with or without patches). Merge Requests are preferred over patches in the BTS as we have configured salsa to run our test suite for britney along with our code coverage report at [3]. More (technical) details can be found in our docs for contribution[4]. Request for info about your britney sources/configs/setups: ------------------------------------------------- We would very much like an updated list of links to your britney sources (e.g. forks/clones), configurations and setups. Our aim is to get a better understanding of what is out there and how you use britney. If you use britney to process data generated by other tools than the ones in use by Debian (like dak), it might be good to mention that as well. Please send this info to debian-release(a)lists.debian.org. Thanks, ~Niels [1] I: [...] - Found a Release file in testing - using that for defaults (Exact format depends on which version you are using) [2] https://salsa.debian.org/release-team/britney2 [3] https://release-team.pages.debian.net/britney2/coverage/ [4] https://release-team.pages.debian.net/britney2/docs/contributing-to-britney… -------------------------------------------------------

Does anyone use patchwork?
by Slávek Banko 20 Dec '18

20 Dec '18

Hi all, as part of updates and migrations that Tim made on the primary server, there was a question as to whether someone is using patchwork service https://patchwork.trinitydesktop.org/ ? Or can this service be droped? I remind that TDE Gitea Workspace (TGW) now serves as the best source code collaboration tool for us. See: https://mirror.git.trinitydesktop.org/gitea/ https://wiki.trinitydesktop.org/TDE_Gitea_Workspace Cheers -- Slávek

FreeBSD 12 :-)
by Dr. Nikolaus Klepp 17 Dec '18

17 Dec '18

Hi all! I just wanted to let you know how TDE works on just-released FreeBSD 12: Basicly everything works as expected, there are just 4 small problems. - For 2 of them I've added bugs + fixes to the bugtracker. - The 3rd is the test "tdeio/kmimetypetest" from "tdelibs", which still fails but mimetipes work after "make install". - the 4rd is again a definition "#define ksize_t socklen_t", but I still have to find where that comes from. So I'm quite pleased :-) Nik -- Please do not email me anything that you are not comfortable also sharing with the NSA, CIA ...

Hi, I have ubuntu 18.4 with trinity R14.0.5. If I want to start the arduino ide from arduino.cc (download and extract arduino-1.8.7-linux64.tar.xz) there comes the splash-screen for one second and it crashes with this message: ~/arduino-1.8.7$ ./arduino Picked up JAVA_TOOL_OPTIONS: TQSettings::sync: failed to open '/etc/tqt3/tqt_plugins_3.5rc.tmp' for writing What I have to install or change? Thank you very much for the great Desktop.
